Figure 1

Phylogenetic tree based on 18S rRNA sequences of Sarcocystis species. The tree is constructed using the Neighbour Joining method. The percentage of replicate trees in which the associated sequences clustered together in the bootstrap test (1000 replicates) are shown next to the branches [27]. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The phylogenetic analysis was conducted using MEGA4 [24].
